Description

H20202DL-R is 10/100 BASE-T DUAL TRANSFORMER MODULE.

This transformer is a component used in Ethernet networking equipment, such as network interface cards (NICs), switches, and routers. This dual transformer is designed to work with both 10BASE-T and 100BASE-TX Ethernet standards.

1. 10/100BASE-T: This refers to the Ethernet standards that the dual transformer is designed to support.

(1) “10BASE-T” is the older and slower standard for Ethernet, supporting data rates of 10 megabits per second (Mbps).

(2) “100BASE-TX” is a faster standard, often referred to as Fast Ethernet, supporting data rates of 100 Mbps.

2. Dual Transformer: This means that the component contains two transformers. Transformers in networking equipment are used to isolate and couple signals between different parts of the circuit. In this case, a dual transformer is designed to handle the signal transformation and isolation for both 10BASE-T and 100BASE-TX Ethernet standards. This makes it suitable for devices that need to support both of these Ethernet speeds.

Features

1. Compliant with IEEE802.3 and ANSI X3.263 standards Including 350uH OCL with 8mA Bias.

2. Dual Channel Interface For 10/100 Mbps Ethernet Applications

3. Comply With ROHS

Schematic
HST-2027DR Transformer

Auto MDI/MDIX:

MDI stands for “Media Dependent Interface,” and MDIX stands for “Media Dependent Interface with Crossover.” In traditional Ethernet connections, devices have to use the correct cable type (either straight-through or crossover) to connect to each other. A straight-through cable is used to connect a computer to a switch or router, while a crossover cable is used to connect two computers directly to each other.
